Network Connection stops working when computer turned off

I am having quite a large problem with my TalkTalk connection. Whenever i turn off my computer, internet access stops for the entire network, anyone who is conencted, however, local access is still possible.

I am also having a problem with the wireless in my laptop also. Whereas every computer on my network is able to access the router wirelessly, my computer (the one that seems to chut down internet access) won't do that, i send packets, but none are received.

How can i fix these two problems, thanks in advance.

EDIT: Also, when i look at my router settings on 192.168.1.1 when the internet access is offline the IP, Primary and secondary DNS come up as 0.0.0.0, while when it is connectedi get proper addresses.

------------------------------------------------------------------------ ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

We would like to see the results from ipconfig /all post back the results in a reply here

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results to notepad and then automatically open notepad.

Now all you need to do is copy and paste those results to a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will be highlighted
Next
From the notepad menu - choose Edit - Copy
Now go back to the forum - reply and then right click in the reply box and paste------------------------------------------------------------------------
